The Test Tube Stand Poly Lab (Product Code: SCL-625/060) is a white plastic stand with 6 places that keeps test tubes upright and organised while reagents are added, reactions are observed and results are compared. Being autoclavable, it can go through sterilisation with the tubes it carries, which makes it equally useful in chemistry and biology practicals. A standard test tube rack for school laboratories, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and suits individual students or small groups working at the bench.

Specifications

Typical Use

A six-place stand is sized for one student's set of tests: running Benedict's, iodine and biuret food tests side by side, comparing the colour of indicator solutions at different pH, carrying out the wet tests of salt analysis, or setting up a small series of dilutions. Lined up in order, the tubes make it easy to compare results and to keep a control next to each sample. In biology and microbiology sessions the same stand holds culture or sample tubes and can be autoclaved afterwards.

Mark each position with the sample name before you start so tubes are not mixed up. Because the stand is plastic, let a tube that has just come out of a flame cool for a moment in a test tube holder before setting it down. Rinse the stand after spills of acids or dyes to keep the white surface clean.

Manufacturer

Jain Scientific Equipments Private Limited manufactures this stand under its ScienceLab brand in Ambala, Haryana, India, alongside a wide range of school and college laboratory apparatus. Read more on the company profile page.

The Crucible Tong (Product Code: SCL-627/061) is a 200mm manual tong in chemical-resistant stainless steel with a low, flattened design, used to place, lift and carry hot crucibles, lids and small porcelain dishes. It keeps the user's hand at a safe distance from the flame and the heated ware during ignition and heating-to-constant-mass experiments. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, these crucible tongs for the lab are used by students, teachers and technicians in school, college and analytical laboratories.

Specifications

Typical Use

The tong is the hand tool for every crucible practical: lifting a crucible of hydrated salt off the pipe clay triangle to cool and weigh it, tilting or replacing a crucible lid while magnesium ribbon burns, moving a hot china dish off the gauze after evaporation, and transferring ignited residues into a desiccator. It is also used to hold a strip of metal in the flame for combustion demonstrations.

Grip the crucible around its body rather than by the rim alone so it cannot tip, and hold the tong near the end of the handles, away from the hot tips. Place heated ware on a heat-resistant surface, never on a wet bench. Because stainless steel is chemical resistant, the tong copes with acidic fumes from heated samples; wipe it clean and dry after each session so residues do not build up on the tips.

Manufacturer

This tong is manufactured by Jain Scientific Equipments Private Limited, known by its trade name ScienceLab, from its base in Ambala, Haryana, India. Our company profile describes the business and its product lines.

Related Laboratory Equipment

Equipment handled with or alongside the crucible tong:

The Test Tube Brush Nylon (Product Code: SCL-630/063) is a round cleaning brush with soft, white nylon bristles, made for scrubbing precipitates, stains and dried residues from the inside of test tubes after practical work. The soft bristles clean the curved bottom and walls of the tube without the harshness of abrasive scouring. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a chemistry consumables supplier in India to schools, colleges and laboratory stores.

Specifications

Typical Use

Clean glassware is the starting point of reliable results — a trace of old precipitate can spoil a salt-analysis test, and the silver-mirror test in organic chemistry only works in a thoroughly clean tube. At the end of each practical, empty the tube, rinse it, add a little detergent solution and work the brush up and down with a twisting motion so the bristles reach the rounded bottom. Rinse with tap water, give a final rinse with distilled water from a wash bottle, and stand the tube upside down to drain.

Push the brush in gently rather than jabbing it against the base of the tube, which protects thin glass from knocks. Rinse and shake the brush after use and hang it to dry so the nylon stays fresh; replace it once the bristles become flattened or splayed.

Supplier

This brush is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. For vendor registration, the company's details are GSTIN 06AAECJ8618A1ZT and Importer-Exporter Code AAECJ8618A issued by the DGFT, under which it ships export orders.

The Label Book Sticker Type (Product Code: SCL-634/065) is a book of white self-stick labels for identifying reagent bottles, glassware, sample containers and specimen jars. Clear labelling is basic good practice in any laboratory: it prevents mix-ups between look-alike solutions and tells the next user what a container holds. The label book is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab consumables supplier in India serving laboratories and schools.

Key Details

Typical Use

Lab assistants use the labels when preparing bench reagents — each bottle should carry the name of the solution, its strength, the date it was made and any hazard warning. Teachers use them to number test tubes and beakers for a class experiment, to mark unknown samples for salt analysis, and to identify specimen jars and slide boxes in the biology room. A well-labelled store is also quicker to audit and restock, which is why a label book belongs in every school chemistry lab equipment list.

Stick the label on a clean, dry surface and press it down firmly from the centre outwards. Write with a ballpoint pen or a permanent marker, and if a bottle is handled with wet hands or near solvents, cover the label with clear tape so the writing stays readable. Remove old labels before applying a new one rather than sticking over them.

Supplier

The label book is supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand, based in Ambala, Haryana, India. Details of the business are on our company profile.

Related Laboratory Equipment

Containers and storage that the labels are most often used on:

• Reagent Bottles For Liquids — bench bottles for prepared solutions
• Reagent Bottles For Solids — wide-mouth bottles for salts and powders
• Reagent Racks — keep labelled bottles in order on the bench
• Volumetric Flask — standard solutions should be labelled as soon as they are made
• Winchester Bottle with Lid — bulk stock bottles that need clear identification

Browse bottles, racks and other consumables in the Chemistry Lab category.

Frequently Asked Questions

How many labels are in each book, and what size are they?
Label count and size are not given in our current listing. Please ask us before ordering so we can confirm them.

What should I write on the labels with?
A ballpoint pen or permanent marker works well on the white surface; avoid water-based ink on bottles that may get wet.

The U Tube Manometer (Product Code: SCL-636/066) is a U-shaped tube of borosilicate glass that measures pressure by the difference in liquid level between its two limbs. It is used for measuring pressure, vacuum, differential pressure and flow in laboratories and plant settings where a dependable, easy-to-read indication is needed. Chemistry, physics and engineering departments use it both for teaching the principle of pressure measurement and for practical checks on gas lines and apparatus. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

With one limb connected to a gas tap, the rise of liquid in the open limb shows the supply pressure above atmospheric; connected to a hand pump or aspirator, it shows the vacuum being drawn. When the two limbs are joined to points on either side of an orifice plate or venturi, the level difference gives the pressure drop from which flow rate is calculated — a standard exercise in fluid mechanics labs. The pressure difference equals the density of the manometer liquid multiplied by gravitational acceleration and the height difference, so students can relate the reading directly to theory. Like other borosilicate glassware, the tube resists chemical attack and changes in temperature.

Clamp the manometer truly vertical, fill it to roughly the middle of both limbs with the working liquid, and check that the two levels match with both ends open before connecting anything. Join it to the apparatus with rubber tubing, tap the glass gently to release trapped bubbles, and read each level at eye level at the bottom of the meniscus for water-based liquids.

Manufacturer

The manometer is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and operates from Ambala, Haryana, India, supplying laboratory glassware and instruments to educational and technical institutions. See the company profile for more information.

Related Laboratory Equipment

Items needed to mount and connect the manometer:

• Rubber Tubing — connects the limbs to the gas line, pump or test point
• Retort Stand — holds the manometer upright on the bench
• Retort Clamp Three Finger — grips the glass tube on the stand
• Vacuum Pump, Hand — for demonstrating vacuum readings
• Open Manometer — an alternative manometer design in our range

Insulated Electric Wire (Copper) (Product Code: SCL-642/069) is copper conductor wire with shock-resistant insulation, supplied by length in metres, for making the electrical connections in chemistry and physics practicals. Teachers and lab assistants use it to join cells, electrodes, bulbs, switches and meters in conductivity, electrolysis and electrochemical cell experiments. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, so it can be ordered together with the apparatus it connects.

Specifications

Typical Use

In the chemistry lab this wire links the two half-cells of a Daniell cell to a voltmeter or galvanometer, connects carbon or metal electrodes to a battery for the electrolysis of water or copper sulphate solution, and completes the lamp circuit used to show which solutions conduct electricity. Schools running electrochemical cell kits and electrolysis apparatus need a steady stock of it, because pieces are cut to length for each set-up and wear out with repeated use. The same wire serves for simple series and parallel circuits in physics.

Cut the length you need, remove a short section of insulation from each end with a wire stripper or cutter, and clean the bare copper so the contact is good. Crocodile clips make quick, secure connections to electrodes and terminals. Always switch off or disconnect the supply before changing connections, and discard any piece whose insulation is nicked or cracked.

Supplier

This wire is supplied by Jain Scientific Equipments Private Limited, which trades under the ScienceLab name from Ambala, Haryana, India and equips school and college laboratories. More about the company is on the profile page.

The Bulb Holder Hanging Type (Product Code: SCL-644/070) is a hanging lamp holder intended for the ionic conductivity demonstration, in which a glowing bulb shows whether a solution conducts electricity. It is waterproof, leakproof and resistant to high temperature, and it is sealed by a hermetic process rather than the ordinary rubber-cap seal found on general holders — useful on a bench where beakers of electrolyte are close at hand. Chemistry teachers use it as part of a chemistry teaching kit for electrolytes and non-electrolytes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In the classic conductivity demonstration the holder and bulb are wired in series with a switch and a pair of electrodes. The electrodes are dipped in turn into distilled water, sugar solution, common salt solution, dilute acid and dilute alkali: the bulb lights brightly for strong electrolytes, glows dimly for weak ones such as dilute acetic acid, and stays dark for non-electrolytes. The hanging design lets the lamp be suspended at eye height where the whole class can see it change.

This demonstration should be set up and run by the teacher. Switch off and disconnect the supply before moving or rinsing the electrodes, never touch the electrodes or the solution while the circuit is live, keep hands and the bench dry, and rinse the electrodes with distilled water between solutions so results are not carried over.

Supplier

The holder is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, India. Buyers completing vendor registration forms can use the company's GST number, GSTIN 06AAECJ8618A1ZT, and its global Legal Entity Identifier, 3358004HRD1JIVXKYX49. The company profile has further details.

Related Laboratory Equipment

Components for building the conductivity circuit:

• Electric Bulb — the indicator lamp fitted in the holder
• Insulated Electric Wire (Copper) — connects holder, switch and electrodes
• Bed Switch — lets the teacher switch the circuit on and off
• Electrode, Carbon, Pair — dipped into the test solutions
• Conductivity Demonstrator — a ready-made alternative for the same experiment

The Bed Switch (Product Code: SCL-645/071) is a common-type single-module switch rated 6A at 240V, with a white ABS body in a glossy finish. Bed switches are traditionally used to switch a lamp on and off from within easy reach; in the laboratory this one gives the teacher a simple, insulated on/off control for lamp and conductivity demonstration circuits. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, alongside the holders, bulbs and wire used to build these set-ups.

Specifications

Typical Use

The switch is placed in series with the bulb holder in the ionic conductivity demonstration so the circuit is only energised once the electrodes are in position, and it is switched off again before the electrodes are moved to the next solution. It also serves as the control switch on demonstration lamp boards and in the simple wiring exercises that accompany an electricity experiment kit in school, where students see how a switch breaks and completes a circuit.

Keep the load within the 6A, 240V rating, make all connections with the supply disconnected, tighten the terminal screws onto clean conductor ends, and keep the switch away from wet areas of the bench. The ABS body is an insulating plastic, but it should still be wiped dry if it is splashed.

Supplier

The switch is supplied by Jain Scientific Equipments Private Limited, whose brand is ScienceLab, based in Ambala, Haryana, India. Read about the company on its profile page.
